XML: Structure Without Meaning

Resources

Specs

• W3C XML 1.0 Spec - The definitive spec. Verbose but authoritative.
• W3C XML Namespaces - How XML avoids naming collisions using URIs. Critical for understanding how RDF serializes to XML.

Tutorials

• W3Schools XML Tutorial - Practical, example-driven intro. Good for syntax basics.
• MDN: XML Introduction - Brief, developer-focused overview.

In Semantic Web

• XML provides structure but no meaning: <name> could mean anything without external agreement. This is exactly the gap that RDF fills by adding URIs to every concept. See RDF: Meaning as Triples.
